2 Kings 5:8-14

8 It was so, when Elisha the man of God heard that the king of Israel had torn his clothes, that he sent to the king, saying, Why have you torn your clothes? let him come now to me, and he shall know that there is a prophet in Israel.  9 So Naaman came with his horses and with his chariots, and stood at the door of the house of Elisha.  10 Elisha sent a messenger to him, saying, Go and wash in the Jordan seven times, and your flesh shall come again to you, and you shall be clean.  11 But Naaman was angry, and went away, and said, Behold, I thought, He will surely come out to me, and stand, and call on the name of Yahweh his God, and wave his hand over the place, and recover the leper.  12 Aren't Abanah and Pharpar, the rivers of Damascus, better than all the waters of Israel? may I not wash in them, and be clean? So he turned and went away in a rage.  13 His servants came near, and spoke to him, and said, My father, if the prophet had bid you do some great thing, wouldn't you have done it? how much rather then, when he says to you, Wash, and be clean?  14 Then went he down, and dipped himself seven times in the Jordan, according to the saying of the man of God; and his flesh came again like the flesh of a little child, and he was clean.
